Tijaabada iska caabbinta dahaarka waxay ku habboon tahay in lagu cabbiro qiimaha caabbinta ee agabyada kala duwan ee dahaarka iyo caabbinta is-beddelka, matoorada, fiilooyinka iyo qalabka korantada si loo hubiyo in qalabkan, qalabka korantada iyo xadhkaha ay si caadi ah ugu shaqeeyaan kana fogaadaan shilalka sida shoogga koronto. Khasaare isugu jira dhimasho iyo dhaawac.
Dhibaatooyinka caadiga ah ee tijaabiyaha iska caabbinta dahaarka waa sida soo socota:
1. Marka la cabbirayo caabbinta culayska awoodda, waa maxay xidhiidhka ka dhexeeya wax soo saarka wareegga-gaaban ee tijaabada caabbinta dahaarka iyo xogta la cabbiray, iyo sababta?
Soo-saarka hadda-gaaban ee tijaabiyaha iska caabbinta dahaarka ayaa ka tarjumi kara caabbinta gudaha ee isha-korontada sare.
Walxaha tijaabada dahaarka badan ayaa ah culeysyo awood leh, sida fiilooyinka dhaadheer, matoorrada leh dabaylo badan, transformers, iwm. Sidaa darteed, marka shayga la cabbiray uu awood leeyahay, bilowga habka tijaabada, isha korantada sare ee tijaabiyaha iska caabbinta dahaarka waa inuu dallaco. capacitor-ka iyada oo loo marayo iska caabbinta gudaha, oo si tartiib tartiib ah u dallacaadda danabka wax soo saarka lagu qiimeeyay qiimaha tamarta sare ee tijaabiyaha iska caabbinta dahaarka.Haddii qiimaha awoodda shayga la cabbiray uu weyn yahay, ama iska caabbinta gudaha ee isha tamarta sare ay weyn tahay, habka dallacadu wuxuu qaadan doonaa waqti dheer.
Dhererkeeda waxaa lagu go'aamin karaa badeecada rarka R iyo C (ilbiriqsiyo gudaheed), ie t = R * C.
Sidaa darteed, inta lagu guda jiro imtixaanka, load capacitive u baahan yahay in lagu soo dallaco in danab imtixaanka, iyo xawaaraha ku dallaca DV / DT la mid ah saamiga ku dallaca hadda I iyo capacitance load C. Taasi waa DV / dt = I / C.
Sidaa darteed, inta yar ee iska caabbinta gudeedku waa, way sii weyn tahay dallacaadda hadda jirta, iyo sida ugu dhakhsaha badan oo aad u xasilloon natiijada imtixaanka.
2. Waa maxay shaqada "g" dhamaadka qalabku?Deegaanka tijaabada ah ee tamarta sare iyo iska caabinta sare, maxaa qalabku ugu xiran yahay "g" terminal?
Dhamaadka "g" ee qalabku waa gabbasho gaashaan, kaas oo loo isticmaalo in lagu tirtiro saamaynta qoyaanka iyo wasakhda deegaanka tijaabada ee natiijooyinka cabbirka.Dhammaadka "g" ee qalabku waa in la dhaafo qulqulka qulqulka ee dusha shayga la tijaabiyay, si aanay qulqulka qulqulku u dhaafin wareegga tijaabada ee qalabka, isaga oo tirtiraya qaladka uu keeno qulqulka qulqulka.Marka la tijaabinayo qiimaha iska caabbinta sare, dhamaadka G wuxuu u baahan yahay in la isticmaalo.
Guud ahaan, g-terminal-ka waxaa la tixgelin karaa marka uu ka sarreeyo 10g.Si kastaba ha ahaatee, kala duwanaanshahan iska caabintu maaha mid dhammaystiran.Waa nadiif oo qalalan, mugga shayga la cabbirayaana waa yar yahay, markaa waxay noqon kartaa mid deggan iyada oo aan lagu cabbirin 500g ee g-dhamaadka;Deegaanka qoyan iyo wasakhda leh, iska caabbinta hoose waxay sidoo kale u baahan tahay g terminal.Gaar ahaan, haddii la ogaado in natiijadu ay adag tahay in la dejiyo marka la cabbirayo caabbinta sare, g-terminal waa la tixgelin karaa.Intaa waxaa dheer, waa in la ogaadaa in terminaalka gaashaandhigga G uusan ku xirneyn lakabka gaashaanka, laakiin wuxuu ku xiran yahay insulator u dhexeeya L iyo E, ama siligga multi strand, maaha fiilooyinka kale ee tijaabada ah.
3. Waa maxay sababta ay lagama maarmaanka u tahay in la cabbiro ma aha oo kaliya caabbinta saafiga ah, laakiin sidoo kale saamiga nuugista iyo index polarization marka la cabbirayo dahaarka?
PI waa index polarization, taas oo tixraacaysa isbarbardhigga caabbinta daaha ee 10 daqiiqo iyo 1 daqiiqo inta lagu jiro tijaabada dahaarka;
DAR waa saamiga nuugista dielectric, taas oo loola jeedo isbarbardhigga u dhexeeya caabbinta daaha hal daqiiqo iyo in 15s;
Tijaabada dahaarka, qiimaha caabbinta dahaadhka wakhti go'an si buuxda uma muujin karo tayada wax-qabadka dahaadhka shayga tijaabada ah.Tani waxay sabab u tahay labada sababood ee soo socda: dhinaca kale, caabbinta caabbinta ee qalabka wax-qabadka ee isku midka ah ayaa yar marka mugga weyn yahay, iyo weyn marka mugga yar yahay.Dhanka kale, waxaa jira habsocod nuugista qarashka iyo habka polaration-ka ee walxaha dahaarka marka danab sare la isticmaalo.Sidaa darteed, nidaamka korontadu wuxuu u baahan yahay in saamiga nuugista (r60s ilaa r15s) iyo index polarization (r10min ilaa r1min) waa in lagu cabbiraa tijaabada dahaarka ee transformer weyn, fiilada, matoorka iyo marar badan oo kale, iyo xaalada dahaarka waxaa lagu xukumi karaa by xogtan.
4. Maxay dhowr baytari oo elektaroonig ah tijaabiyaha iska caabbinta dahaarka u soo saari karaan danab sare oo DC ah?Tani waxay ku salaysan tahay mabda'a beddelka DC.Ka dib farsamaynta wareegga wareegga, korantada sahayda hoose ayaa kor loo qaadayaa wax soo saarka sare ee DC.Inkasta oo tamarta sare ee la dhaliyo ay sareeyso, awoodda wax soo saarku waa ka yar tahay (tamar yar iyo hadda yar).
Fiiro gaar ah: xitaa haddii korontadu ay aad u yar tahay, laguma talinayo in la taabto baaritaanka tijaabada, weli waxaa jiri doona xiirid.
